When your furnace grinds to a halt, it’s pretty clear something is wrong. Other problems, however, may be more difficult to notice at first. There are a few signs you can keep an eye out for that point to an issue with your furnace. Noticing and acting quickly can help make for an easier overall repair process, and in some cases, help you avoid premature furnace replacement. Here are five signs you may need furnace repair:
- Unexpected spike in energy bills.
Your energy bills should be pretty consistent over several months, so a sudden increase can point toward trouble. Keep an eye on your monthly bill for large increases.
- More dust in or around the ventilation.
More and more dust near the air vents could mean the HVAC system’s air filter isn’t working as well. Poor airflow means lower efficiency, so give us a call!
- Odd or unpleasant smells coming from the furnace.
A little burning dust is normal when you first start the furnace each year, but persistent smells may be worth a repair appointment. Pay close attention for burning or rotten egg smells, which could be an electrical problem or a gas leak.
- Loud or annoying sounds that are different from regular operation.
Most furnaces will make a bit of noise when they start up, but loud banging or screeching sounds aren’t normal. A technician can make sure nothing’s damaged or loose.
- Short cycling, where the furnace turns on and off repeatedly.
A normal furnace runs several times each hour for energy-efficient heating. A constant start/stop process is often a sign of a problem. Your thermostat could be malfunctioning, or the furnace’s safety controls could be kicking in.
Don’t ignore these kinds of furnace signs. They may not impact your sense of comfort now, but it could cause major damage before you know it. An important part of good repair service is knowing that an early response can minimize the problem (and your costs to resolve it!). Letting problems go ignored for too long could result in premature equipment failure, requiring early furnace installation.
